.To all yiii/mm 'it may concern.'

Be it known that la llliiini'i-i H lfinnsciy a citizen of the United States, and a resident ol Cedar Falls, in the county ol? llaclchawk and State oi? loiva, have invented a ueiv and useful Improvement in Power-Tr mitting Devices, oit which the following a lull, clear, and exact description.

My invention relates to impro.'enientsl in power transmitting; devices, more particularly to that type ot' device hy .means ot which poiver may he transmitted trom the Wheel of a motorI vehicle to the drive shatt lor operating;l machinery or the like.

An object of my invention ie tov provide a device ot' the character described which is readily adaptable to various sizes ot motor vehicle Wheels regardless oi whether the Wheels are oill artillery, disc, or `Wire con struction.

A :further object oi my invention ir to provide a device oit the typedescribed which may he easily and quickly attached and adjusted in operative position on the ordinary type oil: 'motor vehicle Wheel, the `ivheel lirst heilig jacked oit trom the ground.

A further object o'l my invention to provide device ot the type des-:crilgieifi thatis highly efiicient mechanically, and therehy capable of transmitting a maximum amount et power Yfrom the motor vehicle te the nire chinery which is to he' operated therehy.

A further object et iny invention i: provide. a device ot' the typc esci-filled iu which means is provided tor automatically centering;- the rotating parte thereo'li relative to the motor vehicle, thereh),7 precliidiug` vibration oit the parts. e

A 'further ohject oil my :invention is to provide a device of the type described whi ch is simple in construction and is thoroughly practical commercially.

Other objects and advantages ivill appear in the tolloivinpY slieciiicatiom and the novel features ot the invention will he particu larly pointed out in the appended claims.

My invention is illustrated in the aecompanying drawings forming; parl ot this application. in Which- V Figure l is a side elevation ol' an einhodiment of my invention partially iu section,

Figure 2 is an enlarged sectional view along the line 2 2 of Figure l, and

Figure 3 is a sectional view alone; the line 3*?) of Figure l. l

In carrying out my invention I make use Serial No, 671,155,

oil' the oriflinary type ol motor vehicle hai'- ing;u a `Wheel. Il operatively connected to the propeller shaft (not shoivn) ot the motor vehicle. rthe wheel il is provided with a vehicle tire 2 ot ordinary construction.

Means tor mechanically gripping the tire 2 oil the wheel l so that poiver may he trans niitted therefrom consists iu a pair ol? grip ping nieinhers i having` the contour ot the tread portion oli' the tire 2 (see Figure 2). Those gripping nienihere 3 are each provided with spaced apart openings l arranged in pai and dieposed through the lower portion of the gripping members Fiach oit' the gripping` members 23 is pro-- vided with :i plate having; spa-ced apart oiieuiiips G theretlirough arranged in pairs so that certain ot the openings il may he placed in registration with certain ot the openings fl in such a manner as to permit the longitudinal adjustment ot the plates 5 relativ@ to the gripping` ineiuhers 3. The general contour ot the platea 5 is clearly illustrated in llligure l. lt will he :noted that the plates .fi are lient laterally so that their loivcr ends may clear the ilirotruding portion ot the huh 7 ol" the Wheel l.

'llhe plates Ii are 'Further provided with threaded iioi'tioni-i il and 9 respectively 'at the lower ends. The lfhri-iaded port-ion Fi is possessed et a rigrht hand thread while the portion E) oi the remaining plate is possessed oi' a .le .1 hand threadu ihn interior-lyY thrcaifled tuhular sleeve l having;` right and left hand threads arranged to receive the threaded iioitious t and 9 ol" the plates respectively so that the rotation ol" the tubular meinher l0 may occasion the movement o'i the plates 5 to and away trom each other depeudinej upon the direction ot rotation ol! the sleeve l0.

A metal drum ll closed at one end 12 is arranged to encompass the loivcr portions oiE the plate 5 incliulinpj the threaded portioue il and 9 and the Sleeve lll, .sin openingl?) in the end ivall 'lll oil the plate iieimits'the sleeve l0 lo protrude beyond the rear Wall el? the drinn lll so that it may he manually rotatech thereby adjlisting;v the plates fi from a point exterior ol the drum.

In reference to Figure 2. it will he noted that openings lil are disposed through the peripheral Wall ot the drum Vll so that the portions 8 and 9 of the plates 5 respectively may he admitted thereto. ln making these openings le, a portion oi? the side Wall of the `drum is vbent inwardly and welded to the rear portion of the drum, tl'icreby reenforcing the wall at this point. Likewise, the opening 13 through the rear wall 12 of the drum is provided by pressing back a j )unched out portion of 'the rear wall and welding thisv portion 16 to the rear wall of the drum, thereby reen't'orcing the wall `adjacent the opening 13.

A slideway 17 is formed of the portion of the wall l12 of the drum that is pressed out in forming' the opening` 13 which permits the lparts 8 and 9 of the plates 5 respectively to pass therethrough and which limits the lateral movement of these portions of the plate (see Figures 1 and 2). The drum l1 is ,provided with an opening through its side wall at 18 (see Figure and anv L-shaped recess 19 diametrieally opposed the opening` 18 through the opposite side wall of the vdrum 11. A `member 2O havingr the shape of a double trunniom one disposed at right angles to the other vand constructed after the fashion of .the ordinary gimbal mounting, has trunnions rotatably mounted in the opening 18 and recess 19 of the drum 11. 1t should be noted that the direction of rotation of the drum 11 is in the direction of the arrow V21. 1f the direction of rotation is in the opposite direction, then the re yess 19 must be reversed.

The remaining trunnion of the member20 is rotatably mounted in a pair of aligned recesses 22 provided in one end of the tubular shaft 23 (see Figure 1). An interiorly threaded collar 24 secured upon threads 25 in the exterior wall of the member 23 serves to prevent dislodgment of the member 20 from the recesses 22. It will be noted that I have established a universal joint between the drum 11 and the shaft 23 by the use of the member 20..

The opposite end of the tubular member l23 is connected with a shaft 33 which is rotatably supported in stationary bearings 34 and 35.

A iiy-wheel 36 is disposed upon the shaft 33 intermediate the bearings 34 and the Hattened portion 32 of the shaft. A drive pul ley 37 is carried upon the shaft 33 between the bearing members 34 and 35 so that a Ibelt may be driven by the pulley-37 and in turn drive machinery placed adjacent thereto, such as the ordinary type of farm machinery of stationary nature.

Y vFrom the foregoing description of the various parts of the device, the operation Y thereof may be readily understood. In applying my improved transmission device to the motor vehicle of the ordinarytype, it is first necessary to ack one of the rear wheels or .drive wheels of the vehicle from the ground so that the wheel may be turned bj.' the power plant carried as a part o l the vehicle. The next step in applying my improved transmission is to rotate the sleeve 10 so that the plates 5 move apart from one another, thereby permitting the gripping members 3 to encompass the tread portion of the vehicle tire 2, The tubular member 10 is then turned so that the plates are drawn toward one another and the nippingl members drawn into tight engagement with the vehicle tire and the device is realliI for use. It will be noted that movement o t the plates 5 to and away from cach other is uniform with respect to the drum Al1 and therefore the drum 11 is at all times` on the same axis with the wheel 1.

A belt may be engaged with th: pulleyy wheel 37 and with some niiachinc disposed nearby and rotation of the pulley wheel will cause movement of the belt so that the mfr chine may be driven.

ln takingy down my improved power transmission device, the shaft 23 may be quickly removed .from engagement with the member 20 by merely releasing the collar 214-, thus making the device easy to pack away or store until needed again.

It should be noted that while l have dcscribedione particular embodiment of my invention, that obviously any moditicatitmsl of the particular structure of the device muv be made without departing: from the spirit and scope of my invention as set forth in the appended claims.

I claim:

1. A device of the type described compris ing a pair of cooperating;r clamping platos having substantially the contour of tlu` tread portion of a vehicle wheel. of moans l'or drawing said clamping plates into close cngagement with the tread of said wheel. a universal joint having' one of its cooperating' members attached with said plates. a shaft connected with the remaining member of said universal joint, and means associated with said shaft arranged for drivinglr engage ment with stationary machinery or the like.

2. A device of the type described comprising a pair of cooperating elampiimr members havingr substantially the contour of the tread portion of a vehicle wheel and arranged to engage with the tread portion of a vehicle wheel, means for drawing;r said clampingmembers into close engagement with the tread of said wheel, and a universal joint having one part of its cooperating members attached to said clamping' members and having its axis concentric with the axis of said vehicle wheel when said clamping' members are drawn into close engagement therewith.
